QR Code Generator

Create a QR code for plain text, a link, an email, a phone number, or Wi-Fi credentials, with control over size, quiet zone, and error-correction level. Everything is generated in your browser and downloadable as PNG or SVG — the payload, including any Wi-Fi password, is never uploaded anywhere.

FAQ

Is my content uploaded to generate the code?
No. The QR code is encoded in your browser, so nothing — including a Wi-Fi password — is sent to DevConvertor or any third-party image service. That's the whole reason this is built client-side.
Which error-correction level should I use?
M is a sensible default. Higher levels (Q, H) let a code still scan when it's partly obscured or printed on something that scuffs, but they pack in more modules, making the pattern denser at the same physical size. Use H for stickers and signage, L only when the payload is long and the code will be scanned from a clean screen.
Why does the quiet zone matter?
The blank margin is part of the spec — scanners use it to find the code's edges. Dropping it to 0 often still scans on screen but fails in print against a busy background. 2 modules or more is the safe range.
PNG or SVG?
SVG for anything printed or resized — it stays sharp at any size. PNG for fixed-size use on screen, or where the destination won't accept vector files.
Does a Wi-Fi QR code work on every phone?
iOS and Android both support the WIFI: format from the camera app, and it's widely supported elsewhere — but it isn't a formal standard, so a few older devices will just show the raw text instead of offering to join.
